Photon mass via current confinement
A parity invariant theory, consisting of two massive Dirac fields, defined in
three dimensional space-time, with the confinement of a certain current is
studied. It is found that the electromagnetic field, when coupled minimally to
these Dirac fields, becomes massive owing to the current confinement. It is
seen that the origin of photon mass is not due to any kind of spontaneous
symmetry breaking, but only due to current confinement.Comment: LaTeX2e, 14 pages, No figures, to appear in Physics Letters B. arXiv

Response to the comment on "Do Bloch waves interfere with one another ?"
Here a generalised argument showing the existence of the Bloch superselection
rule is presented, in response to the recent comment by Sowinski. In light of
the role played by the periodic boundary condition, locality and topology in
the system, the claim made in the comment is found untenable.Comment: 2 pages, No figures, To appear in Physics Letters
